Abstract
A rotor according to an aspect of the present invention includes a shaft including: a first shaft hole extending in an axial direction; and a second shaft hole extending radially outward from the first shaft hole and opening to an outer peripheral surface of the shaft. A rotor core includes a plurality of core holes extending in the axial direction and disposed at intervals in a circumferential direction. A plate includes a through-hole overlapping the core hole when viewed in the axial direction, and a flow path connecting the second shaft hole and the through-hole. The plate has an outer edge away from a central axis by a second distance that is shorter than a first distance from the central axis to an outer edge of the rotor core.
